百度痛风的症状是什么配图，仅供参考
ClinicalAn acute gout flare presents as a painful,swollen joint. Patients may complain of severe throbbing pain at night waking them from sleep and pain with ambulation if the foot and ankle are affected. They may note having had similar symptoms during previous gout flares if the condition is long standing. There may be a recent trigger,such as dehydration,alcohol/purine ingestion,illness,or surgical procedure. On examination,patients may have fever,pain with active and passive range of motion of the affected joint,tenderness to palpation,warmth,and erythema. Chronic tophaceous gout appears as subcutaneous nodules that are normally painless but become painful during a flare. The skin overlying the nodules may erode,revealing chalky tophaceous material. Ulceration over a gouty tophus is a risk factor for superinfection. Gout flares can occur in any joint but occur most commonly in the foot and ankle,specifically the first metatarsophalangeal joint.
If a patient with a painful,swollen joint has a history of gout and similar symptoms from previous flares,a gout flare is likely. In the case of no known previous gout history,atypical symptoms,or other risk factors for infection such as immunocompromise or overlying skin ulceration,gout diagnosis must be confirmed with aspiration to rule out septic arthritis,superinfected gout,or a different crystalline arthropathy such as pseudogout/calcium pyrophosphate dihydrate (CPPD) crystal deposition.","department":"
